In a very specific test (unattended_install), all OEM installer
mechanism will present intense guest screen activity, so screen
inactivity for a relatively long time almost always mean something
went very wrong and the installer is stuck.
So create a mechanism to detect screen inactivity for any vm that
takes place in the test - have a timer for each vm that is reset
only if the next screenshot is different than the previous. So,
if the vm got stuck somewhere at the install process, for example:
* Wrong Windows CD Key
* Guest OS does not see a disk controller due to lack of drivers
* BIOS got stuck
And other similar cases, we'll have a test failure before the full
test timeout (that for Windows may be up to 3 hours). So we save
time and know about such situations earlier.
The patch introduces the parameters on base.cfg, subtests.cfg, and
also introduces a sensible default for inactivity treshold (30 min).
